RFC7668 (IPv6 over BLE) in lwip?

[citrullin]

lwip supports the IPv6 over BLE stack. I couldn't find any example for the ESP32. The ESP32 development kit has the lowpan6 files used in some sources. But not the BLE ones. So, I want to know if the ESP32 supports the IPv6 over BLE stack and if not, when the support will be added to the development kit.
